A fluid supply device includes a variable fluid volume to contain a supply of fluid and a variable gas volume to receive pressurized gas to pressurize the supply of fluid. A method of monitoring the fluid supply device may include controlling a gas pressure of the pressurized gas to feed the fluid from the fluid volume, the gas pressure varying in a plurality of pressurization cycles; monitoring a parameter of the pressurization cycles; and determining a change in fill state of the fluid volume as a function of the monitored parameter.
